It handles data rates up to 250 kbps — fast enough for most Modbus, Profibus, and BACnet fieldbus segments, but not for high-speed motion-control links. The 70 mV of receiver hysteresis gives you a solid noise margin on long twisted-pair runs, which matters when the cable snakes past VFDs and contactors. ## Supply rail and temperature range This part runs on a 4.75V to 5.25V supply — it is a 5V-only device, so do not try to power it from a 3.3V rail. If your application stays indoors at 0°C to 70°C, the part still works, but the wider range gives you headroom for worst-case ambient. ## Package and footprint The supplier device package is listed as 8-SOP. It is available in Tape & Reel (TR) or Cut Tape (CT) — the CT option is handy for prototype quantities without committing to a full reel. ## Lifecycle and compliance It is ROHS3 compliant, which means it meets the current EU RoHS exemption rules — no lead, no restricted phthalates.","metaTitle":"SN65LBC184DR RS-485 Transceiver, Half-Duplex, 250 kbps","metaDescription":"Texas Instruments SN65LBC184DR RS-485 transceiver, half-duplex, 250 kbps data rate, 70 mV hysteresis, -40°C to 105°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Type":"Transceiver","Duplex":"Half","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"RS485","Data Rate":"250kbps","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"4.75V ~ 5.25V","Receiver Hysteresis":"70 mV","Operating Temperature":"-40°C ~ 105°C (TA)","Supplier Device Package":"8-SOP","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.67","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.67000","currency":"USD"},{"qty":10,"price":"$4.19800","currency":"USD"},{"qty":25,"price":"$3.96880","currency":"USD"},{"qty":100,"price":"$3.43950","currency":"USD"},{"qty":250,"price":"$3.26312","currency":"USD"},{"qty":500,"price":"$2.92798","currency":"USD"},{"qty":1000,"price":"$2.49600","currency":"USD"},{"qty":2500,"price":"$2.49600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4cb008c54d3679821cafce94125260de.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the SN65LBC184DR a direct replacement for the SN65LBC184?","answer":"The SN65LBC184DR is the tape-and-reel variant of the SN65LBC184 in an 8-SOIC package. Both share the same RS-485 transceiver core, half-duplex architecture, 250 kbps data rate, and 5V supply range. The 'DR' suffix indicates the reel packaging format — electrically and functionally identical to the base part.
